ART OF MANUFACTURING INLAID WORK FOR DECORATIVE PURPOSES.

SPECIFICATION forming part of Letters Patent N0. 488,541, dated December27, 1892.

I Application filed October 8, 1891. Renewed Kay 24, 1392. Serial No.434,174. (No specimens.)

10 all whom it may concern.-

vBe it known that I, HENRY A. COUSINS, a subject of the Queen of GreatBritain, and a resident of New York, county of New York, and State ofNew York, have invented certain new and useful Improvements in the Artof Manufacturing Inlaid Work for Decorative Purposes, of which thefollowing is a specification. M .nvention while relating to the manufan.re of inlaid designs and pictures for domestic and ecclesiasticaldecorations,has reference more particularly to the manner of forming,locating, or building up the outlines of the designs or pictures whichin the finished article constitute the inlaid portions. In the forming,locating, or building up of these designs orpictures, as heretoforepracticed, the metal bands or strips forming the :0 outlines of thedesigns or pictures have been applied to a backing in sections, thelocation and securement in place thereof requiring more or less care,skill and patience according to the quality of the work demanded.

2 5 The prominent objects of my invention are to simplify and improvethe mode of arranging, locating or producing the outlines of the designor picture, so that the same may be accomplished accurately and quickly,and thereby facilitate and cheapen the manufacture,

while at the same time preserving all the required excellence of thefinished work. All these obj ectsand 0theradvantagesfconsequent andincidental I attain byrproviding a pecu- 5 liar matrix, and casting ormolding the outline materialtherein, observing other conditions ofproceeding as follows:-

To produce the matrix, I cover a plate of glass or.othersuitablematerial with wax, mold- 0 ing clay, plaster of paris, or otherappropriate plastic material to the depth of three sixteenths of an inchor thereabout. Upon the surface of this material I produce the desireddesigner picture in outlineby drawing, pounc- 5 ing or transferring inany known way. I next cut through the outlines with a suitably shapedmodeling or engraving tool until the glass or other backing material isexposed and remove all the outlines and all the mate- 5o rial from thecuts. Into the channels thus formed and over all the surface I press acomposition composed of peroxide of manganese,

one part, asbestus or pulverized marble, one and one half arts, andgxideo zinc, one part, which are allf mixed toge er in o a stiif mass withsilicate of potash. After this is pressed in and upon the matrix and hasbecome thoroughly hard I remove the wax or other plastic material andthe outlines of the design or picture will be raised in bands or linesabove the back to the extent of about three sixteenths of an inch,forming what may be called a casting. Into the cells or cavities of thiscasting I then fill and press'the colored cements necessary to completethe design and then allow time for them to harden. panel, slab, or otherarticle of whatever character may be polished in the same way thatmarble is ordinarily polished, care being taken not to grind the slab orarticle below where the outlines appear.

By observing the foregoing directions the outlines are molded and mustas a matter of course correspond in the degree of excellence with thework upon the matrix.

The first casting after becoming hardened may be removed from the glassor other backing and serve as a pattern from which other matrices to anynumber may be produced in rapid succession by simply filling the cellsand cavities therein with the proper materials and then withdrawing thecasting, allowing the matrix thus formed to harden, and so on, therebypermitting of the duplication of the design or picture with very littlelabor in arranging and fixing the outlines. The work is thus producedmore accurately, cheaply and rapidly than is Possible y the oldermethods referred to above, and all the purposes and objects of theinvention alluded to easily accomplished.

The improved method is applicable to all varieties of inlaid work of theclass above pointed out and to all shapes of articles which admit ofmolding. In producing different shapes the expediency of dividing thematrix into sections will readily suggest itself to any who are familiarwith the'art.

Having thus fully described my invention, what I claim as new and desireto seizure by Letters Patent of the United States is, y
